Thread-spool unwinding rack

Separate eight sewing spools and let one spool unwind without tangling neighboring thread.

Assembly

WS-006 dimensioned assembly
  1. Measure the largest intended spool bore and diameter. This example uses bores that clear a measured 1/4 in dowel and spool diameters no larger than 2 1/2 in.
  2. Cut A to 12 in / 304.8 mm by 6 in / 152.4 mm, using measured 3/4 in stock. Mark the front-left corner as X0 Y0 and carry that reference through the work.
  3. Crosscut 8 pegs B to 2 1/2 in / 63.5 mm each. Dress end grain and round the top edges; preserve at least 2 in usable exposed length.
  4. Lay out peg centers on A: X 1 1/2, Y 1 1/2 in; X 4 1/2, Y 1 1/2 in; X 7 1/2, Y 1 1/2 in; X 10 1/2, Y 1 1/2 in; X 1 1/2, Y 4 1/2 in; X 4 1/2, Y 4 1/2 in; X 7 1/2, Y 4 1/2 in; X 10 1/2, Y 4 1/2 in. These are centers, not clear gaps.
  5. Test the actual dowel and a 1/4 in nominal bit in an offcut. Select a fit that seats without splitting; do not force an oversized dowel into a nominal hole.
  6. Set a positive drilling stop at 1/2 in / 12.7 mm. Drill perpendicular blind sockets, leaving 1/4 in / 6.3 mm of A beneath each socket. Clamp the board and use backing under the work.
WS-006 dimensioned parts or elevation
  1. Clean each socket. Apply a small amount of wood adhesive appropriate to the dry indoor use on the embedded 1/2 in of B; keep adhesive out of the exposed gripping area.
  2. Seat every peg to the marked 1/2 in insertion line. Check perpendicularity with a square from two directions and remove squeeze-out before it cures.
  3. Place one spool over each upright peg after cure. Leave its 2 in projection unobstructed; do not force a small-bore spool onto a tight peg.
  4. Let the adhesive cure for its full labeled time. Do not load or twist the pegs while curing; no screw or nail is driven into a peg end.
  5. Take thread from one spool and pull it gently parallel to the tabletop. If it catches a neighbor, move that neighbor to an empty position; do not turn the rack into a powered winding station.
  6. Label the front edge with thread types and keep needles in a separate closed needlebook. Remove loose trailing thread before storage.
